Buying Guide
Key considerations when selecting a residential sub meter:
- Voltage and phase: Most residential sub meters operate on 120/240V single phase or 240V. Confirm compatibility with your service panel and sub‑panel configuration.
- Form factor: ANSI Form 2S plug‑in versus screw‑in 2S sockets; decide based on space, your existing hardware, and ease of installation.
- Measurement scope: Look for CL200 or better accuracy, kWh measurement, and whether the meter supports pulse output, Modbus, or other data interfaces for integration with monitoring systems.
- Data retention: EEPROM or other memory features help maintain data during outages; essential for accurate billing and accounting.
- Display and readability: High‑contrast LCDs and backlit displays improve visibility in various lighting conditions, aiding quick checks for tenants.
- Installation environment: Some meters are better suited for indoor panels, while others are designed for outdoor pedestals or RV setups. Consider enclosure needs and mounting options.
- Cost vs. value: For rental properties, choose meters that offer reliable data export or compatibility with your existing management system, while staying within budget.
